RELATED APPLICATIONS

This application is a division of my co-pending application Ser. No.08/947,113, filed Oct. 8, 1997, now U.S. Pat. No. 6,051,024 which is acontinuation-in-part of my application Ser. No. 08/540,040, filed Oct.6, 1995, now abandoned.

BACKGROUND OF THE INVENTION

In cataract surgery, the practice is to remove the cataractous naturallens and replace it with a man-made lens. The replacement lens is placedinside the natural capsular bag of the natural human lens. Suchreplacement of the natural lens by artificial intraocular lens isdiscussed in my U.S. Pat. Nos. 5,476,514 and 5,047,051.

The present invention represents improvements over my above-mentionedpatents relative to the fixation or anchoring of the lens haptics in thebag, thereby overcoming certain potential disadvantages of plate hapticlenses. My U.S. Pat. No. 5,047,051 discloses a method of fixing a hapticplate in the capsular bag by means of mini-loops at the ends of hapticanchor plates. This enables the bag to fibrose about the loops to fixthe lens in the bag.

In such procedures, plate haptic lenses without loops or fixation meanscan only be implanted in an intact capsular bag with a continuouscircular capsulotomy. Such plate haptic lenses, if placed into acapsular bag having a tear in the anterior capsular rim or posteriorcapsule, can dislocate with resultant serious complication of thesurgery.

During the healing and fibrosis process, the anterior capsule rimbecomes fused to the posterior capsule by fibrosis, and a plate hapticwith an appendage thereof is retained in position by a pocket or tunneldefined by the fibrosis about the haptic or appendage portions betweenthe anterior capsular rim and the posterior capsule.

SUMMARY OF THE INVENTION

As discussed in the foregoing background, a haptic is retained in placeby a pocket or tunnel defined in fibrosis about haptic and appendageportions between the anterior capsular rim and the posterior capsule.

The fibrosis fuses together the anterior and posterior capsules, andsurrounds portions of a plate haptic.

Plate haptic lenses are sometimes desirable because they provide certainadvantages over long loop lenses, including stabilization of thevitreous with substantially less probability of the most seriouscomplications of cataract surgery, these being retinal detachment andcystoid macular edema. Another advantage is the consistent posteriorlocation of the optic, which not only stabilizes the vitreous, butprovides more predictable post-operative, uncorrected visual acuity. Afurther advantage is that the posterior location of the lens results intight contact of the lens with the posterior capsule, thereby resultingin reduced rate of opacification of the posterior capsule with resultantreduced posterior capsulotomy rate.

Improved accommodating intraocular lenses according to the inventioninclude a central optic having normally anterior and posterior sides andextended portions spaced circumferentially about and extending generallyradially out from the edge of the optic. These extended portions haveinner ends joined to the optic and opposite outer ends movableanteriorly and posteriorly relative to the optic.

The lens is surgically implanted in the evacuated capsular bag of thelens of an eye through the anterior capsule opening in the bag in aposition wherein the lens optic is aligned with the opening defined bythe anterior capsular remnant, and the outer ends of the lens distalportions are disposed within the outer perimeter or cul-de-sac of thebag. The lens has a radial dimension from the outer end of each distalor extended portion to the axis of the lens optic so that with the lensimplanted within the capsular bag, the outer ends of the extendedportions engage the inner perimetrical wall of the bag with no orminimal stretching of the bag.

After implantation of the accommodating intraocular lens in the capsularbag, active ectodermal cells on the posterior surface of the anteriorcapsule rim of the bag cause fusion of the rim to the elastic posteriorcapsule of the bag by fibrosis about the lens extended portions in sucha way that these portions are effectively “shrink-wrapped” by thefibrous tissue so as to form radial pockets or tunnels in the fibroustissue which contain the haptic portions with their distal endspositioned within the cul-de-sac of the capsular bag. The lens isthereby fixated within the capsular bag with the lens optic aligned withthe opening in the anterior capsular bag. The anterior capsule rimshrinks during fibrosis, and this, combined with fibrosis about theextended portions, causes some radial compression of the lens so as totend to move the optic relative to the outer ends of the extendedportions in one direction or the other along the optic axis. Thefibrosed, leather-like anterior capsule rim prevents anterior movementof the optic and urges it rearwardly during fibrosis. Accordingly,fibrosis induced movement of the optic occurs posteriorly to a distantvision position wherein either or both the optic and the inner ends ofthe extended portions press rearwardly against and stretch the elasticposterior capsule rearwardly.

During surgery, the ciliary muscle of the eye is paralyzed with aciliary muscle relaxant, i.e., a cycloplegic, such as atropine, to placethe muscle in its relaxed state. Following surgery, a ciliary musclerelaxant is periodically introduced throughout a post-operative fibrosisand healing period (such as two to three weeks) to maintain the ciliarymuscle in its relaxed state until fibrosis is complete. Thisdrug-induced relaxation of the ciliary muscle prevents contractionthereof and immobilizes the capsular bag. By this means, the lens opticis fixed during fibrosis in its distant vision position within the eyerelative to the retina and the lens presses rearwardly against andthereby posteriorly stretches the elastic posterior capsule of thecapsular bag. If the ciliary muscle was not thus maintained in itsrelaxed state until the completion of fibrosis, the ciliary muscle wouldundergo essentially normal brain-induced vision accommodationcontraction and relaxation during fibrosis, and the intraocular lenswould not necessarily fix in the distant position but in some otherlocation along the axis of the eye.

The present invention provides haptic lens features which serve tofixate the distal haptic portions of the lens, thus preventingdislocation and slipping from the proper positions in pockets or tunnelsformed over the haptic lens features by fibrosis. Enlarged and/or distalhaptic portions or protuberances are prevented by their larger dimensionfrom moving or sliding along pockets or tunnels formed by fibrosis aboutproximally inward haptic portions. The enlarged distal structuralfeatures prevent the haptic from sliding inwardly relative to suchfibrosis pockets to fixate and prevent dislocation of the intraocularlens. The enlarged distal structural features may take such forms as:protuberances extending from one or both sides of distal portions ofplate haptics; flexible extensions extending from distal corners of lensplate haptics, which extensions may have protuberances; protuberancesextending outwardly from spring loops or filamentary loops; enlarged endportions or protuberances on distal portions of a plurality of hapticsextending from their proximal ends at an optic; enlarged wide distalportions of haptics tapered to widen in the distal direction; prongprotuberances extending laterally outwardly from distal portions ofhaptics; and notches in side edges of distal portions of haptics.

Other preferred embodiments of the invention include extended or distalprotuberances or knobs and openings defined in distal portions ofhaptics, which serve to fixate the distal haptic portions in theperiphery of the capsular bag between the posterior bag and the anteriorcapsule remnant by the fibrosis process described in the foregoingBackground of the Invention, by the prevention of relative movement ofthe distal portions of the haptics relative to pockets or tunnels formedby fibrosis about proximately inward haptic portions. Other preferredembodiments also include flexible loop haptics extending from diskhaptic portions, knobs provided in the distal portions of a disk hapticelement, openings provided in the distal portions of a disk hapticelement, and knobs and/or openings provided in the distal portions of aplurality of plate-type haptics extending from the optic to their distaledge portions.

DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention provides distal features of haptics of intraocularlenses which serve to fixate the haptic distal portions in the peripheryor cul-de-sac between posterior capsule and anterior capsular bagremnant of the capsular bag. The fibrosis process and procedure foreffecting fibrosis about haptic portions are discussed hereinbefore inthe Background of the Invention.

It is important that distal portions of haptic means be fixated in theperiphery of the capsular bag between an anterior capsular remnant andthe posterior capsule, and that such distal portions or features notmove relative to pockets or tunnels defined by fibrosis about distalhaptic features.

With relatively constant movement of lens haptics on optics, there canbe disengagement of distal haptic portions relative to the bag peripherybetween the posterior bag and anterior remnant, if adequate retention isnot provided. Such disengagement of continued operational force canresult if adequate fixation is not provided, and can result from suchfactors as capsular bag shrinkage during fibrosis causing a tear tooccur in the capsular bag, thus possibly resulting in lens dislocationand the haptic being then positioned in the vitreous in the posteriorportion of the eye, with serious complications.

The embodiments of the present invention herein described provide distalhaptic features which prevent dislocation of haptics by slipping orshifting of distal haptic portions or features relative to fibrosispockets or tunnels wherein distally inward portions of the haptics aredisposed.

Referring to the drawings, and particularly to FIG. 1, a preferredembodiment 10 has a distal portion of a plate haptic 12 withprotuberances 14 thereon. The sectional view of FIG. 2 shows theconfiguration of the protuberances which extend from both sides ofhaptic 12. A protuberance may extend from only one side or surface ofthe haptic. The protuberances will not pass or slide through a fibrosistunnel or pocket disposed about proximally adjacent smaller dimensionedportions of the haptic.

FIGS. 3 and 3A illustrate an embodiment wherein flexible extensions 20extend diagonally from distal corners of lens plate haptics 22, and haveprotuberances 24 at their ends. Extensions 20 position the protuberanceslaterally and distally outwardly of the edges of the haptic, so thatthey are prevented from moving or sliding through a pocket defined byfibrosis about the proximally inward portions of the haptics. FIG. 3Ashows the cross-sectional configuration of the protuberances.

FIGS. 4 and 4A illustrate an embodiment 30 wherein protuberances 32extend outwardly from spring loops or fingers 34 which extend fromdistal portions of plate haptics 36. The protuberances 32 prevent theloop and the distal portions of the haptic plates from moving or slidingrelative to fibrosis pockets formed about the loop and distal hapticportions. FIG. 4A shows in cross-section the configuration of theprotuberances at the ends of the loops. A lens (not shown) generallysimilar to that of FIG. 4, may have a loop element attached to a hapticplate, as by fusion or adhesure, rather than being integrally formedwith the plate.

FIG. 5 illustrates an embodiment 40 of the invention wherein a pluralityof haptics 42 are symmetrically tapered outwardly from relatively wideproximal ends joined to an optic 44 to relatively narrow distal ends orfingers whereon protuberances 46 are disposed. FIG. 5A showsprotuberance details.

FIG. 6 illustrates an embodiment 50, which is not an accommodation lens,wherein each of plate haptics 52 has a wider distal protuberanceportions 54 than proximally adjacent haptic portions. Distalprotuberance portions of the haptics are defined by tapered hapticconfigurations which widen in the distal direction. The wider distalhaptic portion prevents movement of the haptic toward the optic beingretained against movement relative to the pocket defined by fibrosisabout the plate haptic inwardly of the distal portion.

FIG. 7 illustrates another embodiment 60 of the invention wherein prongprotuberances 62, with prongs 64 with rounded ends, extend laterallyoutwardly from distal portions of plate haptics extending from an optic66. The prong protuberances 62 effectively prevent proximal movementtoward optic 66 by inward portions of the haptics relative to thefibrosis pockets formed about proximally inward portions of the haptics.

FIGS. 1, 3 and 4 to 7 illustrate embodiments of the invention whereinnotches 70 are defined in distal edge portions of plate haptics.Preferably, a notch 70 is defined in both lateral distal edge portionsof a haptic, and such notches are preferably defined in lateral edges ofthe distal portions of at least two haptics extending in differentdirections from an optic. As shown, the notch 70 typically has an edgeportion disposed at a substantial angle to or substantially transverselyof the side edge or longitudinal axis of the haptic. Such notches andedge portions are thus disposed to prevent the haptics from becomingdislocated by preventing shifting or sliding thereof relative tofibrosis pockets in which proximally inward haptic portions aredisposed.

FIGS. 8 through 30 illustrate embodiments of the invention which provideprotuberances, knobs, openings or haptic means in distal portions forfixating haptics in the periphery of the capsular bags between theposterior bags and the anterior capsular remnants.

FIG. 8 illustrates an embodiment somewhat similar to that of FIG. 3,wherein there extend from plate haptic portions 74, 76 extensions 78 andcross portions 80 at either end of each of which is a knob orprotuberance 82, shown in cross-section in FIG. 8A, each extendinganteriorly and posteriorly of the plate haptic portion. Theseprotuberances are well-positioned for engagement in the peripheralportion or cul-de-sac of the capsular bag between the posterior bag andanterior remnant, thus to prevent haptic movement through any tunnel orpocket defined by fibrosis about proximately inward haptic portions.

FIG. 9 shows an embodiment with a general configuration somewhat similarto FIG. 5, with transverse cross-portions 84 extending from the outerends of each symmetrically tapered haptic, and having disposed at eachend of each cross-portion a knob 86. These protuberances arewell-adapted to extend into the peripheral portion of the capsular bagbetween anterior remnant and posterior bag to fixate the haptic.

FIGS. 10 and 11 illustrate embodiments wherein step portions 88, 90(FIG. 10) are adapted to engage in the peripheral bag portion betweenthe anterior capsular rim and the posterior capsule, there being similarhaptic portions (not shown) at the opposite side of the optic 92. Aprotuberance or knob 94 depends from step 88 and extends anteriorly andposteriorly. The steps and the knob 94 are adapted to be engaged byfibrosis to fixate the haptic and prevent inward movement of thesecomponents. In the FIG. 11 embodiment, step 96 has on its outer endportion a knob or protuberance 98, and step 100 has depending from itsouter end portion an arm from which depends a knob or protuberance 102,the knobs of FIG. 11 serving purposes similar to those of the knob ofFIG. 10.

FIGS. 12-14 illustrate embodiments wherein flexible or filamentary loophaptics 104, 106 of generally arcuate configuration extend oppositelyfrom an optic 108. Each loop haptic has at its end a knob orprotuberance 110 somewhat similar to that shown in FIG. 8A. The loophaptics extend into the periphery of the bag between the anteriorremnant and the posterior capsule to fixate the haptics and preventmovement of the knobs through fibrosis-defined tunnels defined about theloops. FIGS. 13 and 14 illustrate respectively the correct manner forthe loop haptic to be oriented to engage the bag periphery wherein aportion of the loop and the knob engage the bag periphery. FIG. 14 showsan undesirable disposition of the loop haptic and knob in the fibrosiswhich does not provide optimum and desirable engagement with the bagperiphery.

FIG. 15 illustrates an embodiment which is similar to that of FIGS. 12and 13 except that a plurality of knobs or protuberances 110, similar tothat of FIG. 8A, are positioned in spaced relation along the loophaptics to provide improved fixation of the loop haptic in theperipheral cul-de-sac of the bag.

FIGS. 16 and 16A show an embodiment having a haptic comprising two halfdisk-shaped members 112 from which extend a plurality of loop hapticportions 114. The edge of the disk-shaped portions and the loops areadapted to fit in the peripheral portion of the bag between the capsularremnant and the posterior capsule to fixate the haptic.

FIGS. 17 and 17A illustrate an embodiment which has a disk hapticportion 116 on which are mounted and from which extend a plurality offilament haptic portions 118 of generally arcuate configuration at theend of each of which is disposed a knob or protuberance 120. The loophaptic portions and the knobs serve the purposes outlined relative toembodiments earlier described.

FIG. 18 is an embodiment having a disk haptic 124 wherein are integrallyformed peripheral inclined prong portions 126 extending somewhattangentially with knobs at the ends thereof adapted to fit within theperiphery of the bag between the anterior capsular remnant and theposterior bag for engagement with the periphery for the formation offibrosis thereabout for the purposes earlier described.

FIG. 19 is an embodiment having a disk haptic 130 on the periphery ofwhich are disposed a plurality of knobs 132, such as the knobs of FIG.28, to serve the purposes earlier described in relation to otherembodiments.

FIG. 20 is an embodiment having a disk haptic 134 with a plurality ofcircular openings 136 defined in its distal peripheral portion, thehaptic periphery and these openings become engaged with fibrosis toserve the purposes earlier described.

FIG. 21 shows an embodiment similar to that of FIG. 20, with slot-shapedopenings 138 defined in disk haptic 140.

FIG. 22 is somewhat similar to the embodiments of FIGS. 19 and 21, andhas slot-shaped openings 138 interspersed with knobs 140 in its diskperipheral edge portion.

FIG. 23 shows an embodiment wherein disk haptic portions 141 extendoutwardly from an optic, and extending from their distal edge portionsare a plurality of flexible loop haptic elements 143 with protuberances145 thereon for engagement in the peripheral edge portion of thecapsular bag for fixation of the haptic and centration of the optic.

FIGS. 24 and 25 show embodiments each having four plate haptics 142extending from and equispaced about an optic 144, and having defined intheir peripheral portions slot-shaped openings 145, the haptic edgeportion and the openings being extensible in the bag periphery forpurposes earlier described; the embodiment of FIG. 25 has similarlyequispaced haptics extending from an optic 148, each haptic having aplurality of knobs like those of FIG. 29 on its peripheral portion, theknobs and haptic edge portions serving the purposes earlier described.

The FIG. 26 embodiment is similar to the embodiment of FIGS. 24 and 25,with an optic 150 having four equispaced haptics 152 extendingtherefrom, each having slot-shaped openings 154 therein and a knob 156thereon.

FIGS. 27 and 28 illustrate embodiments wherein plate-type haptics extendoppositely from optic 160 in FIG. 27, and from optic 162 in FIG. 28, theFIG. 27 embodiment having a haptic with slot-shaped openings 164 in itsdistal portion, and the haptics (lower one not shown) of FIG. 28 havinga plurality of knobs 166 in its peripheral portion, the slots and theknobs serving the purposes earlier described.
